I have to create a class of rational numbers with the functionality that it can multiply,add,subtract and divide two rational numbers and give a simplified answer!

i am getting too many errors.

Here is the code:

Code:#include<iostream.h> #include<conio.h> class rational { int num; int denom; int normal() { int d, sign; sign = 1; if (top < 0) { sign = -1; top = -top; d = gcd(top, bottom); top = sign*(top / d); bottom = bottom / d; } unsigned int gcd(unsigned int n, unsigned int m) { if (n == 0) return m; if (m == 0) return n; while (m != n) { if (n > m) n = n - m; else m = m - n; } return n; } public: rational() { num=0; denom=1; } rational (int) { cin>>num; denom=1; } rational (int, int) { cin>>num; cin>>denom; } void setNum(int) { cin>>num; num.normal(); } void setDenom(int) { cin>>denom; denom.normal(); } void add() {rational add; add.a=num*a.denom+a.num*denom; add.b=denom*a.denom; add.normal(); return add; } void sub() { rational sub; sub.a=num*a.denom+a.num*denom; sub.b=denom*a.denom; sub.normal(); return sub; } void mult() { mult.a=num*a.num; mult.b=denom*a.denom; mult.normal(); return mult; } void div() { div.a=num*a.denom; div.b=a.num*denom; div.normal(); return div; } }; int main() { clrscr(); rational x; rational a(3); rational b(3, 4); rational c(2, 4); getch(); }
